Modern experimental techniques have brought atomic quantum gases to the forefront as systems where objects and processes may be studied that find analogues in seemingly distant areas of physics, including condensed-matter physics and early-universe cosmology [i].

YbRh2Si2 is a canonical heavy fermion metal with a field tuned quantum critical point. In recent work we have developed transport measurements on high quality single crystal samples which show it to be a superconductor below 10 mK.

Controlling the outcome of chemical reactions is arguably one of the holy grails of chemical physics. Recent experiments1 have shown that it is possible to direct a photophysical process using infrared light, taking a step towards achieving this goal.

At the forefront of modern materials research is the pursuit of novel quantum states of matter, in which quantum mechanical effects determine the collective physical properties observable at a macroscopic level.1 A prime example in the context of magnetic materials is the quantum spin liquid (QSL).
